Implement Goto Declaration Request

[AnHeuermann]

Description

Implement Goto Declaration Request.

The go to declaration request is sent from the client to the server to resolve the declaration location of a symbol at a given text document position.

In many editors this is something like ctrl+click to jump to the definition of a declaration.

Desired Features

• Jump to definition for Modelica classes
  • Respect scope of the current position. List declarations in scope at the top. Mark known definitions that are not in scope but known.
• Server Test
• Client end to end test

Examples

OMEdit can jump to definition on the diagram view:
